摘要:
Data is recorded on an optical disc using a combination of a user data area where user data is recorded, a control data area for reproduction provided on an inner radius side of the user data area, and an outer guard zone provided on an outer radius side of the user data area as a unit of one recording operation. In this configuration, a track pitch TP of the optical disc is greater than or equal to 0.3 μm and smaller than or equal to 0.4 μm, and the width of the outer guard zone along a radius direction of the optical disc is greater than or equal to a value of (100×TP) and smaller than or equal to a value of (125×TP).

摘要:
An optical disk medium in which a learning area can be expanded, an optical disk information recording method and an optical disk apparatus are provided. A first lead-in area and second lead-in area are provided on the inner side and outer side of a data area. The first lead-in area includes a first learning area, management information recording area and data connection area and the second lead-in area includes a protection area which protects the user data in the inner portion thereof and a second learning area which is provided on the outer side of the protection area and sets an optimum condition for an operation of recording data into the data area. An area in which information indicating the utilization state of the protection area is recorded is prepared in one of the management information recording area and data connection area.
摘要:
An optical disc medium includes a system area and a data area following the system area. The data area includes at least one bordered area and a border area after the bordered area. A record control data in a recording operation of a user data in the bordered area is recorded in the system area. The data area may further include a lead-out area provided on an outermost circumference side in the data area. In this case, the lead-out area may have a record capacity equal to or less than that of the bordered area.

An optical disc medium includes a system area and a data area following the system area. A plurality of sets of an extended record control data area, a bordered area, and a border are possibly set in the data area continuously from the system area, and a first set of the plurality of sets does not include the extended record control data area. A user data is recorded in each of the bordered areas. In each of the plurality of sets other than the first set, a record control data associated with the user data which is recorded in the bordered area of the set is recorded in the extended record control data area.
